SUSPENDED RAILWAY.

broadly in the arrangement and correlation of the various operating parts so that the load of the traveling cars is evenly distributed to a number of supporting wheels, and

so that the supporting rail has this same load evenly distributed over it. This is the feature which I wish to particularly emphasize in the application. There are several features of construction of more or less importance; but this feature of arrangement for even distribution of the weight and load is the feature I wish to herein particularly describe and claim.

In a suspended system of this character, it is usual that the rail or rails be in the form of beams; the span of the rails between adjacent supports being a quantity fixed after consideration of the loads to be carried and the weight of materials desired to be employed. rdinarily` the cars of suspended systems are carried on one or two hangers and the weight of the cars is concentrated at one or more points on the beam rail. Con centration of the load makes it necessary to support the rail at very short intervals and makes the construction heavy, complicated and expensive,

It is one of the objects of my invention to obviate a complicated and expensive coni struction and to substitute therefor a sini ple, light-weight structure which will etticicntly support the trains traveling over its trac-ks. I am enabled to accomplish this object bv the fundamental expedient of dis. tributing the load of each car evenly over the track; so as to form in effect an evenly loaded beam, It is well known that a beam evenly loaded will carry about twice as much weight asy a beam` loaded withl a concentrated weight. By such an expedient, I can either decrease the weight of the rails per linear foot or I may increase the span; or, using intermediate weight and spans, I

l may greatly lessen the deiection of the rails Specification. of Letters Patent.

:'due to the weight of a passing train. It is especially desirable that the rails be kept as nearly as possible in the same horizontal iplane; that there be no undue deiection of the rails under the weight of the train. All ,of these features am enabled to etliciently gcarry out in practice by distributing the load of a train or of a single car over one or more spans of the rail. It may preferably tbe that the distance over which I distribute the weight of a car shall be an even mul- !tiple of a rail span; but this is not necessarily the case, as will hereinafter be point ed out.

I have illustrated preferred forms of my invention in the accompanying drawings, in which,

Figure 1 is an elevation illustrating my improved system, Fig. 2 a side elevation lof the truck, Fig. 3 is a plan of a preferred form of truck which may be used in earrying out my invention, lFig. 4 is a vertical cross section taken on line 4 4 of Fig. 2, i Fig. 5 is a vertical cross section taken on line [5 5 of Fig. 2, Fig. 6 is a section showing 'a preferred form of wheel which may be used in carrying out my invention, Fig. T i is a side elevation of the same. i It will be understood that there are sevn ieral features shown in these drawings and to be hereinafter explained which I do not lherein particularly claim; such particulars including the specific construction of the trucks and wheels. These constructions are ,only included in this description in so far as they cooperate to carry out my main object as hereinabove set forth, and for the purpose 'of showing a practical means of carrying my invention into effect,

In the drawings the numeral may designate towers or other suitable supports upon 'which I mount my rail or rails 11. In the preferred form of trackage I use a base beam 12 surmounted by a channel 13 in which the wheels 14 are ladapted to run. These wheels 14 may be of the general type tand may cooperate with the rail in the genera'l manner set forth in my application S. N. 733.241 tiled November 25, 1912 on traction device; but this is not a necessary feature of my present invention.

lt. is primary feature 0f my invention that the wheels 14 are spaced apart above each car 15 and along the track 11 so as to distribute the weight of 'each car evenly mately `not less than the distance between In witness that 1 claixn the foregoing I `adjacent;` supports for the rail, and the have hereunto subscribed my name this'th ."weght of the car being evenly distributed day of October 1913.
